The five-year-old hit up West Hollywood with his rocker parents Gwen Stefani and Gavin Rossdale, plus his two-year-old brother, Zuma. The family spent the day visiting a crafts center, grabbing ice cream, and picking up some new shoes at Sportie LA.

Seems as if the youngster's new 'do happened just in time for the Fourth of July -- Rossdale rocked his blue punk-inspired coif with a red and white-striped Lacoste polo in L.A. on July 4. (Brother Zuma donned a pint-sized Captain American costume.) See more photos of Kingston's blue mohawk!

The Rossdale boys are no strangers to cutting-edge kid fashions -- Stefani, who has her own successful fashion line called L.A.M.B., has been known to dress them in everything from leggings to mini combat boots.
